Vision Tests Directory
There are many types of vision tests: visual acuity tests, refraction, visual field tests, and color vision tests are a few. These tests help your doctor determine how well your eyes are working. They can help him or her diagnose problems you are having with your eyes such as glaucoma, cataracts, or color blindness. They can also diagnose common problems like nearsightedness or farsightedness. Most children and adults need vision tests yearly to detect any changes in the eyes and to be evaluated for glasses or contact lenses.
